Description

Self extricating accessory for trapped car

The present invention relates to a kind of self extricating accessory for trapped car, particularly a kind ofly can be absorbed in dell and unable when extricating oneself, can make it to roll away from smoothly the self extricating accessory for trapped car of dell at automobile driving wheel.

Kind vehicle skidproof annex in the market, when being absorbed in dell, automobile also can make it to extricate oneself, but because they are heavy, and the form that adopts guard is tied up the periphery at (or grabbing) automobile driving wheel tire, not only oil consumption is many, speed is slow when therefore being with it to travel, and the highway section that has also mustn't pass through, and is very inconvenient, so general automobile is not with antiskid accessory under special circumstances.Be absorbed in dell when can not extricate oneself, rethink toward tire on and be with antiskid accessory, owing to tire the latter half is absorbed in the hole, so be difficult to accomplish in case sail sidewalk into.Especially solo running is absorbed in dell in the open air, and is isolated, worried especially, want to even out the hole smoothher or in the hole, insert the thing of the sandstone that can increase friction force a bit or faggot and so on, limit by condition, want the external force traction of seeking help, chance is difficult meets, even meet, also steel rope may not be arranged.In this case, roll away from wanting from then on a fully loaded automobile cheated, by no means easy.

Task of the present invention is will provide a kind of can only idle running and unable when extricating oneself after automobile driving wheel is absorbed in dell, uses this self extricating accessory for trapped car just can make automobile utilize the propulsive effort of self successfully to roll dell away from.

The present invention is achieved using the following method: as everybody knows, why automobile misses the bus, and is because drive wheel is absorbed in after the dell, because the hole wall more suddenly or more sliding, tire and ground-surface friction force are reduced greatly, automobile can only seesaw among a small circle in dell in addition, and its body movement speed is very little, and natural inertia is also very little, therefore there are not enough uplift forces that drive wheel is come out from dell, can only dally in former hole, and the commentaries on classics hole is dark more more, automobile also just be can not extricate oneself more.If this moment we the annex of a similar tank track be fixed on its drive-wheel tyre above, when drive wheel rotates again, toothrow penetrates in the darker soil layer, just can increase tire and the friction force of cheating wall greatly, again automobile this moment under the assistance of the inertia of preshoot, just can realize utilizing automobile self propulsive effort that it is extracted the purpose of dell.

The concrete structure of self extricating accessory for trapped car is shown in Figure of description.1. curved plate wherein, 2. 3. toothrow locatees protruding nail, 4. pull bar ring, 5. pull bar, 6. slide fastener, 7. fastening loose joint.

Be described in detail as follows in conjunction with Figure of description: after automobile driving wheel is absorbed in dell, because the drive wheel of bogie all is the both sides at axle drive shaft, and every side generally has two wheels, its outmost steel ring that is taken turns has 4～6 macropores, and inside and outside all do not have parts and block, and therefore only rare one or two holes are exposed at beyond the dell when being absorbed in dell.1. we just can be buckled in the curved plate of this self extricating accessory for trapped car on its tire like this, 3. two protruding nails in location snapped in certain decorative pattern of tire separately, and make the center of a macropore of curved plate centrally aligned steel ring 1..Because curved plate arc radius 1. is just consistent with this tire outside diameter, add the effect 3. of the protruding nail in location, 1. curved plate just is attached to above the tire, can not slide front and back.Again 6. slide fastener is outwards passed from the steel ring hole inboard, collude in slide fastener appropriate location 6., 7. fastening loose joint is tightened, 1. curved plate is attached to above the tire of drive wheel firmly with spanner with fastening loose joint hook 7..At this moment start automobile, because 2. the toothrow that 1. curved plate is gone up can large tracts of land catch ground.Make the friction force surge, drive wheel no longer skids, motion obliquely upward under the effect of automobile self propulsive effort.When drive wheel rotates to certain angle, this self extricating accessory for trapped car no longer works, but because this moment, drive wheel improved many (it is so not dark that this is equivalent to dell) to vehicle body on the one hand, the cover tire of drive wheel contacts with new ground on the other hand, its friction force is big many when skidding than originally, adding automobile self has the bigger inertia to preshoot, makes original drive wheel be absorbed in the automobile of dell like this, has rolled dell away from regard to the propulsive effort that utilizes self.Unload self extricating accessory for trapped car, automobile again can cruising.

This self extricating accessory for trapped car is looked particular case, can use in automobile one side, also can use simultaneously both sides; Can advance, also can retreat.
